Two grassfires in Okanagan Mountain Provincial Park have been contained by firefighters after burning through 10 hectares of land.

Air tankers, three helicopters and two fire crews were brought in to fight the fires, which started early Thursday afternoon southeast of Swick and Lakeshore roads in Kelowna.

The fires blazed through the site of a disastrous 2003 forest that led to the evacuation of about 50,000 people and gutted 200 homes and a lumber mill.

No evacuation orders have been made for the area in the latest fire, although two property owners have left voluntarily, according to a release from the Regional District of Central Okanagan.

Firefighters were expecting to work on extinguishing the fire overnight.
